Summary

PROOF OF CONCEPT/IDEA, this can obviously be optimized.

This was a big project of mine back in the day to cool my place and myself, this is top notch for sleeping, the fans are more silent than the typical fan you'd buy in a shop and the cooled surface is much wider/taller. It's surprisingly powerful, helped me all throughout 2020 & 2021. Though my bill saw the difference since it was basically running all day long throughout summer, wonder how I could alleviate the energy cost. I haven't run the numbers but it seemed to add 20 bucks a month for a 24/7 usage.

PARTS IN THIS PROJECT:

• 8x 120mm computer fans (parts designed for ARCTIC P12 PWM PST Value Pack 2020)
• 4x 10mm wide 1m long rods (I went with aluminum)
• Holding material (metal wire/thin string/rope, here probably 4m20 of string, and 1m10 of wire on it)
• Hot glue
• Power wire
• Solder
• Shrinking wrap
• AC adapter (12V 1A, I think it needs 0.64 total or something, refer to the fans you buy)

Every part is designed to run wires/rope around to bind the fans together. There are accommodating holes & grooves on every part.

It's obviously dangerous in its current form, you have to be careful, I've cut myself twice and have broken one blade (had to replace an entire fan), the included stand isn't even the best I came up with, really. This array just does the job, but it can again be well optimized.

That said I love it and don't know what I'd do without it, it cools me very well by +30°C, again I can sleep relatively well by the same temp with this fan.

All of my designs have roughly a 0.1 to 0.3 mm offset/compensation for things to fit together according to how my printer prints. I have no idea if this is a universal problem or not.

Supports on my designs are always minimal if not nonexistent. Here there is none needed.
